AUXILIARY AIR AND DRAINAGE DEVICE FOR GASOLINE-ENGINE INTAKES.

Application filed February 2, 1925. Serial No. 6,324.

The invention is designed to improve the efliciency of gasoline engines,particularly such engines as are used with automobiles. With suchengines under varying conditions difiiculty is encountered in the factthat the raw gasoline is carried into the engine. The present device isdesigned to avoid this by the introduction of air at a point between theintake manifold and the carburetor and 1.0 at the drainage side of theconnection between the carburetor and the manifold. here the carburetoris of the vertical type this is in the connection nextto the engine andwhere the carburetor is or" the horizontal 5 type at the bottom of theconnection. Features and details of the invention will appear from thespecification and claims.

The invention is illustrated in the accompanying drawings as followsFig. 1 shows a side elevation of an engine cylinder withthe invention inplace.-

I Fig. 2 an enlarged view of the connection between the carburetor andthe manii'old.

Fig. 3 an enlarged View of the gasket in which the device is preferablyarranged.

Fig. t a section on the line 44 in Fig. 3. 1 marks the engine cylinder,2 the intake manifold, and 3 a connectionbetween the manifold and thecarburetor 1-, the carburetor having a flange 5 and a connect-ion 6 andthese are secured together by screws 7. A gasket 8 is arranged betweenthe flanges 5 and (3. This gasket is made up of the top and bottom metalplates 8" with an intervening layer of yielding material, usually asheet of asbestos, the plates being secured together by crimping thecentral tube of one over the other. An opening 9 extends through theyielding material and between the plates 8. A corrugated plate 10 isarranged along one side of the yielding material. the corrugationextending into the opening dividing the opening into the unobstructedpassage 11 at one side and the unobstructed passages 1212 at theopposite side. It will be noted that there is no obstruction preventingthe flow of gasoline to the opening 'so that it may be readily drainedthrough the opening when there is not sullicient air current through theopening to spray the liquid.

In the operation of the device the incoming gh velocity air through theopening induced by the suction in the manifold picks up and sprays oratomizes any liquid gasoline that may be flowing upwardly along the wallof the connection and creates turbulence in the mixture passing up theconnection. Further any liquid which may'assume a volume which will bedeposited in the manifold and 1n the starting operation, or otherconditions of the engine may flow backwardly from the manifold orconnection will follow down the drainage side of the connection which isthe bottom or engine side of the connection until it-reaches thisopening. Here if the engine not running the gasoline will flow outthrough the opening rather than back into the carburetor thus floodingthe carburetor. If the engine is running even slowly but suflicient tocreate a current through the opening this current will pick up thegasoline and atomize it. Thus in the starting of the engine the largequantities of gasoline which are deposited and drain back through theopening are picked up and atomized by this opening. The separation ofthe air passage into several passages thereby dividing the stream of airinto the separate streams adds to the turbulence induced by the ejectedair and thus increases the efficiency of the device.

hat I claim as new is An auxiliary air and fuel drainage device adaptedto be inserted between the carburetter and intake manifold, the airinlet opening in the gasket being on the drainage side of the manifold,said device comprising a gasket consisting of top and bottom metalplates and an intermediate layer of yielding material, said yieldingmaterial having an unobstructed spray and drainage opening therethrough,and a corrugated metal plate, the corrugation of the plate beingarranged in the opening.

In testimony whereof I have hereunto set my hand. i
